Relationship Between Body Height and the Length of Canine Teeth in Terms of Jaw and Gender Using of Cone-beam Computed Tomography in Patients Referring to the Department of Oral and Maxillofacial Radiology, Tabriz Faculty of Dentistry in 2018-2019

Abstract

Introduction: One of the determinative factors in identifying individuals is the relationship between the size of different parts of the body and their height that has been considered by forensic medicine investigators in the past two decades. One of these can be the canine teeth. Considering that canine teeth show the most sexual dimorphism among the teeth, this study was conducted to determine the relationship between height and length of canine teeth by separation of the jaw and gender by imaging with Cone beam computed tomography. Materials and methods: In this cross-sectional study, images from 133 patients who referred to the Tabriz Dental School for various reasons (for example, insertion of implants, etc.) and were prescribed CBCT imaging and according to entry and exit criteria were entered into the study. Demographic characteristics of individuals, including age and sex, were recorded. Then the height of the persons was measured in the standing and in the position with the Frankfort Plane parallel to the ground and entered in the checklist. Then the canine teeth were measured on CBCT images. Data were analyzed by using statistical software SPSS17. The significance level of study was P <0.05. Results: The mean length of canine teeth in both genders, males and females and also in the maxilla of males was 28.18 mm but, in the mandible of males, maxilla of females and in the mandible of females was 25.84, 25.39 and 24.03 mm, respectively. The results of statistical analysis showed that there is a significant difference between the mean length of canine in both genders and in both maxilla and mandible (P <0.001). There was a positive correlation just between the maxillary canine length and height of the women and this relationship was not significant in the other groups. Conclusion: In both genders, maxillary canines were higher than mandibular canines. There was a correlation between the maxillary canine length and height of the women.
